Identifier, protein and gene names [?]

Protein name
RecName: Full=D-phenylhydantoinase;
EC 3.5.2.-;
AltName: Full=Hydantoin-utilizing enzyme HyuA;
Gene name

Comments [?]

Function Catalyzes the stereospecific hydrolysis of the cyclic amide bond of D-hydantoin derivatives with an aromatic side chains at the 5'-position. Has no activity on dihydropyrimidines. The physiological function is unknown.
Catalytic activity RHEA:51664: D-5-phenylhydantoin + H2O = H(+) + N-carbamoyl-D-phenylglycine
Cofactor a divalent metal cation
Note: Binds 2 divalent metal cations per subunit.
Subunit Homotetramer.
Ptm Carboxylation allows a single lysine to coordinate two divalent metal cations.
Similarity Belongs to the metallo-dependent hydrolases superfamily. Hydantoinase/dihydropyrimidinase family.
